Need Help ASAP!

Hello guys!..
I own a mpc 2500.. today i decided to update the official os to jjos free version to test it out!
The only thing i've got from all this stuff is a white screen without loading anything... buttons are lighted but it seems like it doesnt have os or something like that

Is there anyway to fix this?

thanks in advnace

Your MPC is shot! I´d buy it off from you for $ 1.

So either sell it to me or adjust your screen contrast...

you are a god man!
thank you very much! it was the contrast

Contrast? Hold down STOP and turn data wheel a few times. Is that an original screen or a third party upgrade?
